Brief Summary

This behavioral study on healthy participants aims to provide a baseline reference for assessing alterations of decision-making performance in pathological conditions. To this purpose, this single center non-interventional behavioral study will assess the extent to which decision-making performance is affected by distinct experimental manipulations, as well as by ageing effects, in 200 healthy individuals. The main questions it aims to answer are:

• to what extent is decision-making performance stable, within individuals, regardless of non-economic manipulations concerning stimuli perceptual features as well as type of processing and motor response required to participants?
• are these manipulations additionally influenced by participants' age? Healthy participants will be recruited for distinct behavioral studies assessing the effects of the aforementioned manipulations of distinct metrics of decision-making performance, such as loss aversion, risk aversion, and delay discounting.

Outcome Measures

Primary Outcomes (1)

• Individual index of loss aversion

  This variable reflect the spontaneous disposition to overweigh potential losses, compared with equivalent gains in decision-making, resulting in the tendency to avoid potential losses more than approach potential gains.

  Behavioral-study day 1

Secondary Outcomes (2)

• Individual index of risk aversion

  Behavioral-study day 1

• Individual index of delay discounting
